Purity Operating Environment delivers software-defined storage and flash management purpose-built to power Pure’s shared accelerated storage.

Software That’s Generations Ahead

Purity delivers comprehensive, rich data services to all workloads – even as it provides global flash management to your arrays. Moreover, Purity enables consistent low latency, data protection, and non-disruptive “everything” – and its resilience means full performance through array maintenance and failures. Need more proof of its power? Purity’s industry-leading data reduction and total efficiency are typically 2x better than the competition.

Shared accelerated storage like FlashArray//X would not be possible without the breakthrough performance and resiliency of Purity for FlashArray™. The consistent sub-1ms latency, unprecedented density, and GBs of bandwidth //X offers are powered by Purity//FA, DirectFlash with NVMe, and, in 2019, by the non-disruptive addition of NVMe-oF*.


Disk-to-disk-to-tape is so Y2K. It’s time to modernize with flash-to-flash-to-cloud. Pure CloudSnap™ and StorReduce™ enable fast restore on-premises, cost-effective and reliable retention, and new uses for your data in the cloud.

Flash-to-Flash-to-Cloud Data Protection Flash-to-Flash-to-Cloud Data Protection


Now every enterprise can achieve RPO zero and RTO zero across racks, data centers, or metro regions, effortlessly and affordably. Purity//FA 5 introduces multi-site stretch cluster with Purity ActiveCluster – always-on, Active/Active protection that’s built-in and a snap to setup. No additional cost, and no external controllers or third site required – Purity ActiveCluster is included in your Evergreen™ Subscription.

Purity Run Extends Purity//FA Services

Purity//FA ships with Purity Run – a platform for running applications on FlashArray that’s ideally suited to lightweight, data services-oriented processes. Purity Run apps include: Windows File Services, adding SMB and NFS support to FlashArray; Snap to NFS; VM Analytics; and CAT for SAP.

Purity Run Open Platform for Applications Purity Run Open Platform for Applications


Purity and VMware Virtual Volumes (VVols) now enable unprecedented levels of management simplicity for your VMs. Assure that your SLAs are met – per VM – via Purity’s data services, storage policy-based management, and flexible data portability. And the best part? Set it up in minutes.

Purity Reduce:
Unbeatable Total Efficiency

Purity delivers the industry’s most comprehensive data reduction and total efficiency – typically 2x better than the competition. And unlike other vendors, it’s built-in, always-on, and requires no tuning. You’ll buy less storage now, and less storage in the future!

Purity Assure: Goodbye Downtime

With proven 99.9999% availability for FlashArray, inclusive of generational upgrades, Purity keeps your data and applications safe, secure, and available at all times – without performance loss. In addition, Purity provides always-on QoS and effortless control over your workloads. No more noisy neighbors, maintenance windows, and long weekends in the data center!


Purity for FlashArray delivers an effective technology platform for compliance regulations, including the new GDPR policy, and has earned an NIAP / Common Criteria Certification. Data security is provided by always-on FIPS 140-2 validated AES-256 data-at-rest encryption, KMIP integration, and rapid data locking.

Purity Protect: Never Be Without Your Data

Purity ActiveCluster is just one part of the data protection delivered by Purity. For added peace of mind, Purity offers space-efficient disaster recovery and protection – both locally and globally. Snapshots and replication (to FlashArray™ or an NFS target) are built-in, data reduction-aware, and a snap to set up. Get protected within minutes with policy-based automation.


We believe in API-first. Purity’s available cloud connections, integrations, and REST APIs ensure that Pure Data-Centric Architecture will integrate with what matters in your data center. VMware vCenter, vRealize, OpenStack, and many more. Best of all, Purity’s simplicity means that FlashArray and FlashBlade™ are fully automatable.

The Power Behind FlashBlade Scale

FlashBlade is the industry’s most advanced scale-out storage, delivering unprecedented performance for modern data applications. Its massively distributed architecture enables consistent performance for all analytics applications using NFS, S3/Object, SMB, and HTTP protocols. FlashBlade is as simple as it is powerful, and all driven by Purity//FB2.

Purity Delivers Scale-Out Storage

FlashBlade is built on scale-out metadata architecture, capable of handling 10s of billions of files and objects while delivering maximum performance. Storage services at every layer are elastic, thanks to the distributed transaction database built into the core of Purity for FlashBlade. As with //X, Purity provides global flash management and effortless scale: simply adding additional blades grows system capacity and performance, instantly.

Object Store is now Fast Store

Archive. Cold Storage. Object systems today are built for cheap and deep storage. With the emergence of modern data analytics like Spark and deep learning, organizations can finally unlock the potential hidden in their data. Purity//FB 2 now supports S3 protocol, delivering ultra-fast performance for objects.

FlashBlade – Now with Snapshots

Delivering rapid innovation is part of who we are. Purity//FB 2 introduces a wave of new enterprise features, like snapshots, SMB, LDAP, network lock management (NLM), and IPv6, to extend FlashBlade into new use cases. In particular, snapshots bring ultra-fast performance for data protection and recovery, accelerating workflows in enterprise deployments like software development and databases.


What if storage software could talk directly to raw flash? With DirectFlash™, now Purity can. Purity interfaces directly with flash media via PCIe/NVMe (and NVMe/oF to DirectFlash Shelf), providing global flash management, I/O scheduling and optimization, and end-to-end garbage collection. In effect, we’ve eliminated the performance challenges inherent in a “black box” SSD – by redefining the SSD. DirectFlash means faster, more efficient storage from the same raw flash!
